Earlier this week it was reported that the largest ice shelf in Canada has collapsed. Using microscopy, photosynthetic pigment analyses, and molecular techniques we examined the planktonic communities present in Milne Fiord to determine the biotic characteristics of the epishelf lake and the sea water below. The Planet Earth-observation company has just released new imagery of the broken Milne Ice Shelf in the Arctic. Rejoice; warmth brings biodiversity. The sooner we make them, the better it will be overall.”. Additionally, imagery from USNIC and JPSS shows exactly where the iceberg disconnected from the shelf’s larger mass.
